Retractable Sootblower

Clyde Bergemann has several types of retractable sootblowers available for cleaning heat exchangers mainly within power, waste, biomass and industrial boilers. All of our retractable sootblowers were designed according to the conditions of a steam generator to ensure trouble-free operation.

Clyde Bergemann retractable sootblowers offer excellent results in cleaning performance. Using the most effective cleaning nozzle on the market, cleaning impact is maximized with a minimal amount of blowing media.

Every retractable sootbower comes standard with the industry leading multiple blowing pattern (multi-progressive helix indexing) system. By indexing inside the gearbox using a clutch, we eliminate problems such as pinion and gear rack failure found in other systems.

Retractable sootblowers are available in different versions for specific requirements and travels up to 66 ft.

Principle of cleaning

The lance tube with two opposite high-performance nozzles is helically moved into the flue gas path

Consequently the blowing process begins shortly after the two nozzles have passed through the boiler wall

During the blowing process the lance tube continues to move helically into the flue gas path

On reaching the front-side end position the direction of movement changes and the lance tube returns to its rest position

Features

Integrated droop correction for defined guidance of nozzle head close to the optimum sootblower center line

Integrated multi-blowing pattern for more uniform and complete cleaning with minimum erosion impact to the heating surface
